</ul>
<p>1、修改工程的info.plist中”Supported interface orientations”的值（一般在工程的Taget-&gt; General -&gt; Deployment Info -&gt; Device Orientation处打钩来选择设备支持）</p>
<p>2、实现工程的AppDelegate文件中的（application:supportedInterfaceOrientationsForWindow:）方法，在此方法中返回程序支持的方向枚举。</p>
<p>iOS 横竖屏设置</p>
<figure class="highlight objectivec"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br></pre></td><td class="code"><pre><span class="line"><span class="built_in">UIInterfaceOrientationMaskLandscape</span> 	 	支持左右横屏</span><br><span class="line"><span class="built_in">UIInterfaceOrientationMaskAll</span>  				支持四个方向旋转</span><br><span class="line"><span class="built_in">UIInterfaceOrientationMaskAllButUpsideDown</span> 	支持除了UpsideDown以外的旋转</span><br><span class="line"></span><br><span class="line"><span class="comment">//支持旋转</span></span><br><span class="line">-(<span class="type">BOOL</span>)shouldAutorotate&#123;</span><br><span class="line">   <span class="keyword">return</span> <span class="literal">YES</span>;</span><br><span class="line">&#125;</span><br><span class="line"><span class="comment">//支持的方向</span></span><br><span class="line">- (<span class="built_in">UIInterfaceOrientationMask</span>)supportedInterfaceOrientations &#123;</span><br><span class="line">    <span class="keyword">return</span> <span class="built_in">UIInterfaceOrientationMaskAllButUps</span></span><br></pre></td></tr></table></figure>



<p>1、先在AppDelegate中重写<code>supportedInterfaceOrientationsForWindow</code>方法</p>
<figure class="highlight objectivec"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br></pre></td><td class="code"><pre><span class="line">-(<span class="built_in">UIInterfaceOrientationMask</span>)application:(<span class="built_in">UIApplication</span>*)application supportedInterfaceOrientationsForWindow:(<span class="built_in">UIWindow</span>*)window&#123;</span><br><span class="line">   <span class="keyword">return</span>	<span class="built_in">UIInterfaceOrientationMaskAll</span>;	<span class="comment">//支持全方向</span></span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

<p>2、创建一个UINavigationController的子类BaseNaviController，设置self.window的RootViewController为BaseNaviController;</p>
<p>然后，我们在BaseNaviController.m文件里面也实现着两个方法：</p>
<figure class="highlight objectivec"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br></pre></td><td class="code"><pre><span class="line">-(<span class="type">BOOL</span>)shouldAutorotate</span><br><span class="line">&#123;</span><br><span class="line">    <span class="keyword">return</span> [<span class="keyword">self</span>.topViewController shouldAutorotate];</span><br><span class="line">&#125;</span><br><span class="line"></span><br><span class="line">-(<span class="built_in">UIInterfaceOrientationMask</span>)supportedInterfaceOrientations</span><br><span class="line">&#123;</span><br><span class="line">    <span class="keyword">return</span> [<span class="keyword">self</span>.topViewController supportedInterfaceOrientations];</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>



<p>3.在第一个页面写上，支持旋转 但是这个页面只支持竖屏，代码：</p>
<figure class="highlight objectivec"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br></pre></td><td class="code"><pre><span class="line"><span class="comment">//支持旋转</span></span><br><span class="line">-(<span class="type">BOOL</span>)shouldAutorotate&#123;</span><br><span class="line">	<span class="keyword">return</span> <span class="literal">YES</span>;</span><br><span class="line">&#125;</span><br><span class="line"></span><br><span class="line"><span class="comment">//支持的方向因为界面A我们只需要支持竖屏</span></span><br><span class="line">- (<span class="built_in">UIInterfaceOrientationMask</span>)supportedInterfaceOrientations &#123;</span><br><span class="line">	<span class="keyword">return</span> <span class="built_in">UIInterfaceOrientationMaskPortrait</span>;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>



<p>4.第二个页面我们写上，我们所需要的横屏效果，代码：</p>
<p>当只需要锁定屏幕的旋转不需要设置屏幕的旋转方向 ( 方向固定是竖直)</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line">// 是否支持屏幕旋转</span><br><span class="line">-(BOOL)shouldAutorotate &#123;</span><br><span class="line">    return NO;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

<p>开启屏幕旋转并设置屏幕旋转支持的方向</p>
<figure class="highlight objectivec"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br><span class="line">16</span><br><span class="line">17</span><br><span class="line">18</span><br><span class="line">19</span><br></pre></td><td class="code"><pre><span class="line"><span class="comment">// 是否支持屏幕旋转 (返回 NO 后面俩方法不调用，后面只支持竖直方向)</span></span><br><span class="line">-(<span class="type">BOOL</span>)shouldAutorotate &#123;</span><br><span class="line">    <span class="keyword">return</span> <span class="literal">NO</span>;</span><br><span class="line">&#125;</span><br><span class="line"><span class="comment">// 支持屏幕旋转的方向</span></span><br><span class="line">- (<span class="built_in">UIInterfaceOrientationMask</span>)supportedInterfaceOrientations &#123;</span><br><span class="line">  <span class="comment">//  通过设置返回的枚举值来改变屏幕旋转支持的方向</span></span><br><span class="line">  <span class="comment">//（iPad上的默认返回值是UIInterfaceOrientationMaskAll，</span></span><br><span class="line">  <span class="comment">//  iPhone上的默认返回值是UIInterfaceOrientationMaskAllButUpsideDown）</span></span><br><span class="line">    <span class="keyword">return</span> <span class="built_in">UIInterfaceOrientationMaskAll</span>;</span><br><span class="line">&#125;</span><br><span class="line"></span><br><span class="line"><span class="comment">// Returns interface orientation masks. （返回最优先显示的屏幕方向）</span></span><br><span class="line"><span class="comment">// 同时支持Portrait和Landscape方向，但想优先显示Landscape方向，那软件启动的时候就会先显示Landscape，在手机切换旋转方向的时候仍然可以在Portrait和Landscape之间切换；</span></span><br><span class="line"><span class="comment">// 返回现在正在显示的用户界面方向</span></span><br><span class="line"><span class="comment">//此方法也仅有在当前viewController是rootViewController或者是modal模式时才生效.</span></span><br><span class="line">- (<span class="built_in">UIInterfaceOrientation</span>)preferredInterfaceOrientationForPresentation &#123;</span><br><span class="line"></span><br><span class="line">&#125;;</span><br></pre></td></tr></table></figure>



<p>对于非modal模式的viewController:如果不是rootViewController,则重写supportedInterfaceOrientations,preferredInterfaceOrientationForPresentation以及shouldAutorotate方法, 按照当前viewController的需要返回响应的值.如果是rootViewController,则如下重写方法:</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br></pre></td><td class="code"><pre><span class="line">-(NSUInteger)supportedInterfaceOrientations&#123;</span><br><span class="line">        return self.topMostViewController.supportedInterfaceOrientations;</span><br><span class="line">&#125;</span><br><span class="line">-(BOOL)shouldAutorotate&#123;</span><br><span class="line">        return [self.topMostViewController shouldAutorotate];</span><br><span class="line">&#125;</span><br><span class="line">- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation&#123;</span><br><span class="line">return [self.topMostViewController preferredInterfaceOrientationForPresentation];</span><br><span class="line">&#125;</span><br><span class="line">-(UIViewController*)topMostViewController&#123;</span><br><span class="line">//找到当前正在显示的viewController并返回.</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

<p>显而易见, 我们巧妙的绕开了UIKit只调用rootViewController的方法的规则. 把决定权交给了当前正在显示的viewController.<br>对于modal模式的viewController. 则按照需要重写<code>supportedInterfaceOrientations</code>,<br><code>preferredInterfaceOrientationForPresentation</code>以及<code>shouldAutorotate</code> 方法即可.</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br><span class="line">15</span><br><span class="line">16</span><br><span class="line">17</span><br><span class="line">18</span><br><span class="line">19</span><br><span class="line">20</span><br><span class="line">21</span><br></pre></td><td class="code"><pre><span class="line">UIApplication* app = [UIApplication sharedApplication];</span><br><span class="line"></span><br><span class="line">// 判断设备方向状态，做响应的操作</span><br><span class="line">if(app.statusBarOrientation == UIInterfaceOrientationPortrait || app.statusBarOrientation == UIInterfaceOrientationPortraitUpsideDown)&#123;</span><br><span class="line"></span><br><span class="line">&#125;else if(app.statusBarOrientation == UIInterfaceOrientationLandscapeLeft || app.statusBarOrientation == UIInterfaceOrientationLandscapeRight)&#123;</span><br><span class="line"></span><br><span class="line">&#125;</span><br><span class="line"></span><br><span class="line">UIInterfaceOrientationPortrait---------按钮在下</span><br><span class="line">UIInterfaceOrientationPortraitUpsideDown---------按钮在上</span><br><span class="line">UIInterfaceOrientationLandscapeLeft---------按钮在左</span><br><span class="line">UIInterfaceOrientationLandscapeRight---------按钮在右</span><br><span class="line"></span><br><span class="line"></span><br><span class="line">// 通过状态栏电池图标来判断屏幕方向</span><br><span class="line">    if ([UIApplication sharedApplication].statusBarOrientation == UIInterfaceOrientationMaskPortrait) &#123;</span><br><span class="line">        // 竖屏 balabala</span><br><span class="line">    &#125; else &#123;</span><br><span class="line">        // 横屏 balabala</span><br><span class="line">    &#125;</span><br></pre></td></tr></table></figure>



<p>AppDelegate.m中有如下方法可以设置整个app的方向。</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span class="line">- (UIInterfaceOrientationMask)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window &#123;</span><br><span class="line">      return UIInterfaceOrientationMaskLandscape;</span><br><span class="line">&#125;</span><br><span class="line"></span><br><span class="line">该方法实质上是制定window的方向，虽然一个app有多个VC，但是window都只有一个，所以这个指定了window的方向，那所有VC的方向就都是统一的。</span><br></pre></td></tr></table></figure>



<p>已废弃方法</p>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br></pre></td><td class="code"><pre><span class="line">shouldAutorotateToInterfaceOrientation //在iOS6之前</span><br></pre></td></tr></table></figure>
